overview
CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built by certified auditors for your Web3 product.

We architect and deploy battle-tested smart contracts that form the immutable foundation of your dApp. Our code is built on Solidity 0.8+ with OpenZeppelin libraries, following security-first development practices to mitigate risks like reentrancy and overflow.

Deliver a secure, auditable, and gas-optimized contract suite in as little as 2-4 weeks.

Our process includes:

  • Full lifecycle development: From specification and architecture to deployment and verification on-chain.
  • Comprehensive testing: Unit, integration, and scenario testing with tools like Hardhat and Foundry.
  • Pre-audit readiness: Code is structured and documented to streamline formal security audits by firms like CertiK or Quantstamp.
  • Support for all major standards: Custom ERC-20, ERC-721, ERC-1155, and bespoke logic for DeFi, NFTs, DAOs, and more.

PROVEN METHODOLOGY

Our Development & Integration Process

A structured, four-phase approach designed to deliver a secure, scalable, and production-ready privacy-preserving recommendation engine, minimizing your technical risk and accelerating time-to-market.

01

Architecture & Protocol Design

We design the core cryptographic architecture, selecting and integrating the optimal privacy primitives (zk-SNARKs, MPC, HE) for your specific use case. This phase defines the data flow, trust model, and on/off-chain components to balance performance with provable privacy.

Smart Contract & Backend Development

Development of the on-chain verifier contracts (Solidity/Cairo) and the off-chain proving/processing backend. We implement the chosen privacy protocol, ensuring gas efficiency for on-chain verification and high throughput for recommendation generation.

Privacy-Preserving Social Recommendation

Frequently Asked Questions

Get clear answers on how we build secure, compliant, and high-performance social recommendation systems for Web3.

We implement a multi-layered privacy architecture. Core recommendations are computed using Zero-Knowledge Proofs (ZKPs) and Fully Homomorphic Encryption (FHE) to process encrypted user data without decryption. User graphs and preferences are stored in decentralized, permissioned data pods (like Ceramic or Tableland), with access controlled by user-held keys. This ensures we never see or store raw, personally identifiable information (PII), maintaining compliance with regulations like GDPR and CCPA by design.
